PATENT PNEUMATKC CASH-CARRIER APPARATUS.

SPECIFICATION forming part of Letters Patent No. 378,792, dated February28, 1888.

Application filed April 1 1887.

To ail whom it'may concern.-

Be it known that I, GEORGE B. KELLY, of Boston, in the county of Suffolkand State of Massachusetts, have invented certain new and usefulImprovements in Pneumatic Oash-0arrier Apparatus, of which the followingis a full, clear, and exact description.

' This invention relates to improvements in pneumatic tube dispatchapparatus more particularly for use in the transmission of cashcarriersor small parcels, 8m, through the tube from the operation of a bellowsor other airmotor; and the invention consists in the combination,with apneumatic tube provided with a valve for closing the receiving end oropening in such tube where the carrier, &c., is inserted fortransmission therethrough, and either with or without a valve adapted toopen and close communication between such tube and the operating-bellowsor other air-motor, of means connected to either one or both of saidvalves and having air communication with the bellows or other air-motor,all arranged for operation on either one or both of said valves, allsubstantially as hereinafter fully described.

In the accompanying sheet of drawings is illustrated the presentinvention.

Figure 1 is a front view of aseries of receiving ends of pneumatic tubesfor transmission therethrough of a carrier, &c., at a cashiers desk orcentral station. Fig. 2 is a horizontal section on line 2 2, Fig. 1.Figs. 3 and 4 are vertical cross sections on lines 3 3 and 4. 4,respectively, Fig. 1 being enlarged, Fig. 3 rep resenting the parts intheir normal position, and Fig. 4 in their position when the bellows orother air-motor is being operated for the transmission of acaslrcarrier, 850., through the tube.

In the drawings, A A represent the ends of a number of pneumatic tubesfor transmission therethrough of cash-carriers or other articles, andeach is secured in the top of its respective head or receiver l3,whiehreceiver has a chamber, 0, and a tube, D, forming a continuation of thepneumatic tube A, the receiver being open at its lower end. These headsor receivers B are secured in proper position by screws a in front of abox or case, E, and the chamber 0 of each receiver has communicationwith a separate chamber, F, of the case E by Serial No. 283,294. (Nomodel.)

an opening, G, through the front of the case. The opening H in thebottom of the head has a valve, J, pivoted at b to the head, theswinging up of which valve closes and swinging it down opens saidopening H. The carrier, &c., to be transmitted through the tube is inserted at this opening H into the tube A, and the valve J then swung up,closing said opening.

K is a valve adapted to move up and down in guideways d at and over anopening, L, in the rear side of the case E, one to each chamber F, andwhen down to close and when moved up to open said opening L. The severalopenings to the chambers F open into a common or conducting chamber orpipe, M, back of thesaid openings, which is connected by a pipe, N, to asuitable operating-bellows or other air-mo tor (not shown in thedrawings) in such man ner that air from such bellows,when operated, willpass to said conducting-chamber M, and thence to whichever chamber F isin communication therewith by having its valve K raised or open.

Each valve J has an arm, 1?, which is connected by a link,f, to themoving or under side, R, of a bellows or other ,exhaustible andcollapsible chamber, Q, attached and secured to the under side of thebottom board of the case E, one bellows to each valve, the chamber Qcommunicating with its respective chamber F by a passage or opening, M.Piv oted by one end to the inner side of the bottom or movable board Itof the bellows Q is a link or pitman rod, 9, which at its other end ispivoted to one end of a horizontal lever, S, adapted to swing on apivot, h, on an arm, Z, of a partition of the case, the other end ofwhich lever is connected by a link or pitman rod, m, to an arm, n, onthe back side of the valve K,near its lower edge or end. Swinging up thevalve J, through its link f, connecting it with the bellows, opens it,which in turn, through the link g and lever F connection to the valve K,raises and opens the same. A spring, T, secured to the bottom of the boxat r, its free end it extending into and pressing upward against an eye,U, secured to the movable board R of the bellows, helps to force backand hold the bellows closed,ready for operation again after the valve Jis lowered or opened.

. of the operator, which is accomplished by the combination of the smallbellows or expanding chamber Q, as will be explained. Operating thebellows or other air-motor to propel the carrier, 850., through thetube, air in passing through the chamber F to its pneumatic tube A alsopasses down through the opening M into the bellows Q, and opens it andso holds it open, and by their connection therewith the valve J is heldclosed and the valveK opened, and so held so long as the'bellows orother airmotor is operated, and as soon as the operating-bellows ceasesthe bellows Q closes and the valves return to their normal positionsshown in Fig. 1.

The link f is connected to the valve J and bellows Q in such manner thatwhen the bellows is opened out, as shown in Fig. 4, the link will bestraight, or substantially so, with the movable board It, acting as atoggle-lever and exerting the most pressure at the time the mostpressure is desired upon the Valve J, to hold it closed and the valve Kopened.

This invention is more particularly adapted for use at the cashiers deskor central station, where the several pneumatic tubes meet which leadfrom the several sales counters or stations, for in such case theconducting-chamber M has communication with the several chambers F andis closed to the passage of air to the same by the valves K, so that theair from theoperating-bellows, 8tc., only passes to the pneumatic tubehaving its valve K opened and desired to be used for the transmission ofthe carrier, 820.

When used at the sales-counter or single station, the valve K can bedispensed with, as the chamber F would then communicate directly withthe air-motor, needing no valve; but it is preferable to use the smallbellows Q in connection with the valve J, as described; or, if desired,only valve K can be connected to the bellows Q.

With the operating-bellows or other airmotor in operation and the valveJ closed, there is more or less pressure from such bellows to open suchvalve, and therefore, to hold it firmly closed by the bellows Q, thearea of the movable board of the bellows must be larger than the area ofthe valve J for it to overcome the pressure on the valve.

The bellows Q, can be constructed in any suitable manner, so that itwill open and close for operation, substantially as described.

The valve K can be connected directly to the movable board R of thebellows Q, dispensing with the lever S and its connection, which,perhaps, might be preferable, being simpler in its construction.

Having thus described my invention,what I claim is-- 1. The combination,with a pneumatic tube for the transmission of a carrier, 8tc.,therethrough, provided with a valve arranged to close and open thereceiving end or opening for the carrier, 820., of means connected tosaid valve and adapted to be operated by air from the operating-bellowsor other air-motor, by which said valve is held closed, for the purposespecified.

2. The combination, with a pneumatic tube for the transmission of acarrier, 8m, therethrough, provided with a valve for opening and closingcommunication between said tube and the operating-bellows or otherair-motor, of means connected to said valve and adapted to be operatedby air from the operating-bellows or other air-motor, by which saidvalve is held open, for the purpose specified.

3. The combination, with a pneumatic tube for the transmission of acarrier, 8zc., therethrough, provided with a valve arranged to close andopen its receiving end or opening for the carrier, 850., and a valve foropening and closing communication between said re ceivingtube and theoperating-bellows or other air-motor, of means connected to the twovalves and adapted to be operated by air from the operating-bellows orother air-motor, by which said valves are held respectively closed andopened, for the purpose specified.

4. The combination, with a pneumatic tube for the transmission of acarrier, 8tc., therethrough, provided with a valve arranged to close andopen its receiving end or opening for the carrier, 850., and a valve foropening and closing communication between said tube and theoperating-bellows or other air-motor, of a bellows or expanding andcollapsible chamber connected to said valves and adapted to be operatedby air from the operating-bellows or other air-motor for operation onsaid valves, substantially as and for the purposespecified.

In testimony whereof I have hereunto set my hand in the presence of twosubscribing witnesses.
